javascript - 使用js对象值

Question

嗨，我有这个 js 对象，我想将元素“价格”“保存”在数组中，这样我就可以操作它们。我怎样才能做到这一点？

$(function(){
    $("#elastic_grid_demo").elastic_grid({
        'filterEffect': 'scaleup', // moveup, scaleup, fallperspective, fly, flip, helix , popup
        'hoverDirection': true,
        'hoverDelay': 0,
        'hoverInverse': false,
        'expandingSpeed': 500,
        'expandingHeight': 500,
        'items' :
        [
            {
                'price'         : '10.95',
                'title'         : 'Azuki bean',
                'description'   : 'Swiss chard pumpkin bunya nuts maize plantain aubergine napa cabbage soko coriander sweet pepper water spinach winter purslane shallot tigernut lentil beetroot.Swiss chard pumpkin bunya nuts maize plantain aubergine napa cabbage.',
                'thumbnail'     : ['images/small/1.jpg', 'images/small/2.jpg', 'images/small/3.jpg', 'images/small/10.jpg', 'images/small/11.jpg'],
                'large'         : ['images/large/1.jpg', 'images/large/2.jpg', 'images/large/3.jpg', 'images/large/10.jpg', 'images/large/11.jpg'],
                'button_list'   :
                [
                    { 'title':'Demo', 'url' : 'http://porfolio.bonchen.net/' },
                    { 'title':'Download', 'url':'http://porfolio.bonchen.net/'}
                ],
                'tags'          : ['Portrait']
            }, /* ...more items*/

使用 Array.map (请参阅 MDN )从对象数组创建数组:

var prices = [yourArrayOfObjects].map(function(v) {return v.price;});
